rdf.geneontology.org not available (timeout occured)

[JervenBolleman]

Describe the issue/bug

502 Proxy error, probably because the backend is down.

Expected behavior

Access to a sparql endpoint available at https://rdf.geneontology.org/blazegraph/sparql

To Reproduce

visit https;//rdf.genenontology.org

Screenshots

If applicable, add screenshots to help explain your problem.

Additional context

It might also be time to drop blazegraph and replace it with a different engine such as RDF4j or Jena.

Can duplicate. Oddly, it does not report on uptimerobot as being down.

@JervenBolleman While there's still some stuff we want to follow up on, I believe that the endpoint should be up for you again?

[JervenBolleman]

@kltm and it's down again.

[kltm]

The query http://rdf.geneontology.org/blazegraph/sparql?query=select%20%2A%20where%20%7B%20%3Fs%20%3Fp%20%3Fo%20.%7D%20LIMIT%201 seems to be operating for me. Perhaps it's the particular query?

[JervenBolleman]

Ah @kltm it is when there is no query at all that it is not responding.

[kltm]

@JervenBolleman I think this is just the way this endpoint has always operated. Is there a use case for the empty call?

[JervenBolleman]

When going from a service call in one code editor -> select the endpoint string open in new tab expect output. 502 proxy error very unexpected. Leads to confusion and here we are ;)

Noting here that GO is currently deprecating our public SPARQL endpoint, with plans to deprecate all related products in the future.
